Polk, 12 others sign with Birds

The Philadelphia Eagles completed their draft weekend by agreeing to terms with a baker's dozen undrafted free agents, including a running back with huge potential.

Washington running back Chris Polk ran for more than 4,000 yards in his career, but injury concerns left him waiting for a phone call after all seven rounds of the draft were completed.

The 5-11, 222-pound Polk topped 1,400 yards in his junior and senior seasons, and was a first-team All-Pac 12 pick last year, when he ran for 1,488 yards and 12 TDs and caught 31 passes.

He was projected as high as a second-round pick and no less than a fourth, but shoulder and knee injury histories might have worried teams. There were also reports that Polk has a degenerative hip injury, which he has denied.

Another interesting acquisition was Oregon cornerback Cliff Harris, a consenus All-American in 2010 when he had six interceptions and returned 29 punts for an 18.8-yard average, including four touchdowns.

But Harris had a series of legal issues related to multiple traffic citations, was suspended and then dismissed from the team after hardly playing in 2011.

Philadelphia, which has not re-signed veteran free agent fullback Owen Schmitt, added a pair of fullbacks: Emil Igwenagu of Massachsetts and Jeremy Stewart of Stanford. The 245-pound Igwenagu had 38 catches for the Minutemen. The 218-pound Stewart ran for nine touchdowns.

The Birds loaded up on wide receivers, signing five of them: Elvis Akpla of Montana State; McKay Jacobson of Brigham Young; Damaris Johnson of Tulsa; Aaron Pflugrad of Arizona State; and Darnell Williams of Louisiana College.
